Description
This guide to celestial navigation has been popular ever since it first appeared in 1969. Revised in 1982, Celestial Navigation is intended to answer the need for a quick, easy, and thorough explanation (with realistically worked problems) of the practice of celestial navigation at sea, using simple and inexpensive equipment. Extracts from the Nautical Almanac and Pub. No. 249, as well as some blank workforms, are included.
